Two Cases of Trichosporon Beigelii Pneumonia in Immunocompromized Hosts

Abstract

Two cases of Trichosporon beigelli pneumonia in severely immunocompromized patients are reported. At autopsy, Trichosporon beigelii was detected in all lobes in one patient who had a small cell lung cancer. Polymycotic infection involving Trichosporon beigelii and Aspergillus was proved in the other patient who had a non-Hodgkin's lymphoma. Miconazole therapy was not effective against Trichosporon beigelii infection in both cases. Although diagnosis and management are difficult, Trichosporon beigelii must be considered as a cause of visceral opportunistic fungal infection.
